摘要
The Sloan Digital Sky Survey (SDSS) will carry out a digital photometric and spectroscopic survey over pi steradians in the northern Galactic cap. An array of CCD detectors used in drift-scan mode will image the sky in five passbands to a limiting magnitude of r' similar to 23. Selected from the imaging survey, 10(6) galaxies, 10(5) quasars and selected samples of stars will be observed spectroscopically. I describe the current status of the survey, which recently saw first light, and its prospects for constraining models for dark matter in the Universe.
